External Yaw Rate Sensor Module : Communication interrupted
Check the wiring and connectors between external yaw rate sensor and central ECU and between steering angle sensor and central ECU for open circuit and physical damage (including check for chafing damage), check the power supply of the ESP sensors 8,3V - 14,5V, if error still active, replace external yaw rate sensor, if error still active, replace central ECU.
What you'll see
No driver-visible symptom recorded.
System reaction
ESP control off ESP Warning Lamp.
Diagnostic depth
The error is set if the central ECU does not receive any messages from the yaw rate sensor.
Damaged wiring and/or connectors between yaw rate sensor and central ECU or between steering angle sensor and cenral ECU, yaw rate sensor is not connected to the central ECU, damaged yaw rate sensor, damaged steering angle sensor, damaged central ECU.
